“OKOS” is a wake-up call application for iOS and Android. You can choose a voice and time (JST) to customize your wake-up call. About one hundred characters voices are available in “OKOS”, so users can enjoy a different voice every day.
“OKOS” has added a new voice option, bird songs! You might wake up more comfortably to the sound of bird songs. Popular budgie voices are recorded, too.
You can download and try the app for free. (After your registration, a test call will ring in 1 minute and then you’ll hear a voice message for 10 seconds. ) The subscription fee for its unlimited plan is 960 yen per month.
